Test Method for Antibacterial Activity of Photocatalytic Materials

ISO 27447The ISO 27447:2019 standard outlines a method to determine the antibacterial activity of materials containing a photocatalyst or photocatalytic films by enumerating bacteria after exposure to ultraviolet (UV) light.

This standard applies to testing photocatalytic ceramics and other non-porous materials treated with photocatalysts, such as textiles, glass, and plastics.

Test Description

  • Bacteria (Escherichia coli or Staphylococcus aureus) are inoculated onto the test and control surfaces. Other bacteria strains can be requested.
  • The samples are exposed to UV light for a set duration, after which viable bacteria are extracted from the test and control materials and enumerated.
  • The antibacterial activity of the photocatalyst after UV irradiation is calculated according to criteria in the standard.
  • The antibacterial effect is also assessed in the dark and incorporated into the calculations.
